SHUTTER-FASTENER.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed November 5, 1907. Serial No. 400,792.

To all whom it may concern:

Be it known that I, HILLIARD FRANCIS CHREITZBERG, a citizen of the United States, and a resident of Winston Salem, in the county of Forsyth and State of North Carolina, have invented a new and Improved Shutter-Fastener, of which the following is a full, clear, and exact description.

This invention relates to shutter fasteners and more especially to fasteners by means of which shutters, window blinds and the like can be locked in closed positions, and which are operable from the inside only, of the windows.

An object of the invention is to provide a simple, strong and durable fastener by means of which the shutter, blind, door or the like can be securely locked in position, and which cannot be opened from the out side without breaking the shutter or other closure, or the frame of the same.

A further object of the invention is to provide a device of the class described which looks the shutter or thelike and which is held in an operative position gravitationally.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views,

' and in which Figure 1 is a transverse section of a portion of a window-frame and a shutter and showing my invention applied thereto; Fig. 2 is an enlarged cross section on'the line 22 of Fig. 1; Fig. 3 is a perspective view of a portion of a window-frame and the shutters therefor, showing my invention applied thereto; Fig. 4 is an enlarged longitudinal section showing the fastener; Fig. 5 is a similar view showing certain of the parts in different positions; and Fig. 6 is a similar view showing certain of the parts in still other positions.

Referring more particularly to the drawings, 1 represents the framing or trim of a window of the usual type. It will be understood that while my invention is particularly useful in connection with window shutters or blinds, it can also be used for locking other closures such as swinging doors and the like. The shutters 2 are pivotally mounted by means of hinges at the opposite sides of the window-frame, and swing toward each other when being closed. The shutters may be of any preferred or common form and operate in the usual manner. One of the shutters has a lateral flange or rib 3 which engages at the outer side of the other shutter to hold the latter in position; consequently, it is necessary to lock the first shutter only, to hold both in a closed position.

An opening 4 is formed in the wall under the bottom of the window-frame, and a similar opening 5 registering with the opening 4 is formed in the lower window-frame member 6. A hook or latch 7 having an attaching plate 8, is secured at the inner lower edge of the first shutter by means of screws 9 or in any other suitable manner. By the first shutter is meant the shutter which has the flange 3 serving to hold the other shutter in a closed position. The hook 7 has a shoulder 10 and a rounded nose 11, for a purpose which will appear hereinafter.

Arranged within the opening 4 near the outer end of the same, is a socket 12 having a laterally disposed end 13 presenting an opening 14 adapted to permit the insertion therethrough of the hook 7. The end 13 of the socket is arranged substantially closing the end of the opening 4 and has lateral extensions 13 rigidly secured to the windowframe or Wall by means of screws or the like. At the opposite side, the socket has recesses or notches 15. An elongated member or lever 16 having a head 17, is arranged within the opening 4 and extends through the opening 5. The head 17 has trunnions 18 which seat in the recesses 15 and pivotally support the lever. The inner projecting end of the latter has a handle 19 by means of which it 9 can be easily, manually operated. The head 17 is provided with a slot 20, and has the end beveled to permit the rounded nose 11 of the hook 7 to ride easily thereover and to depress the head to permit the hook to slip into engagement with the slot 20.

The arrangement of the lever is such, that the portion on the side of the trunnions 18 remote from the shutters is of greater weight than the remainder of the lever, and in consequence, the inner end of the lever is normally depressed, holding the head in an ele- Vated position, as is shown most clearly in Fig. 4. When the shutter is closed, the engagement of the hook 7 with the head depresses the head temporarily to permit the engagement of the hook with the slot 20, the shoulder 10 of the hook engaging at the outer edge of the slot to lock the shutters in position. When it is desired to release the shutter it is merely necessary to raise the inner end of the lever, thereby depressing the head and permitting the shutters to move freely out of engagement with the fastener. As no part of the fastener appears at the outside of the window or window-frame, it is impossible to open the shutters from this side without breaking the same, or the frame. It will be noted that no springs are used to facilitate the operation of my invention, and that the number of operating parts is a minimum. Consequently, the device will not get out of order easily and is capable of efficient service for extended periods.

A plate 21 is mounted upon the frame member 6 covering the opening 5, and has an elongated slot 22 permitting the projection beyond the frame member 6, of the lever 16. The slot serves as a guide for the lever and permits the raising or lowering of the same when the fastener is manually operated. The plate 21 is securely mounted in position by means of screws 23 or in any other suitable manner.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1. A fastener, comprising a catch adapted to be mounted upon a shutter, and a pivoted member adapted to be arranged in an opening of a window-frame and presenting means for directly engaging said catch to lock the shutter in a closed position, said member being gravitationally held inan operative position, and extending through said opening to the side of the window-frame remote from the shutter.

2. A fastener, comprising a catch adapted to be mounted upon a shutter, and a pivoted member adapted to be arranged in an opening of a window-frame and presenting an edge for directly engaging said catch to lock the shutter in a closed position, said pivoted member being gravitationally held in an operative position and extending through said opening to the side of the window-frame remote from the shutter and being arranged to be displaced by said catch to permit the same to engage said edge.

3. A fastener, comprising a catch adapted to be mounted upon a shutter and having a rounded edge, and a lever adapted to be arranged in an opening of a window-frame and having a head, said lever being pivoted in said opening in such a manner that said head is normally held in an elevated position by gravitation, said head having a slot adapted operatively to be engaged by said catch, said head having a beveled edge adapted to be engaged by said rounded edge of said catch, whereby said lever is displaced when the shutter is being closed, to permit said head to be operatively engaged by said catch.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
